Self-suturing anchor device for a catheter

摘要

A self-suturing anchor device includes rotatable ring adapted to automatically deploy sutures to secure a catheter. The rotatable ring is utilized in connection with a ratchet mechanism which allows movement of the rotatable ring in a first direction while preventing movement of the rotatable ring in the opposite direction. The rotatable ring is also utilized in connection with a bearing member to facilitate smooth and efficient rotation of the rotatable ring. An extension saddle is utilized to provide a desired amount of displacement between suture securement points to minimize pivotal movement of the catheter. The rotatable ring is wider than its height to minimize kinking of the catheter tube and to relieve pressure when pressed between the patient and a support surface. In another embodiment, a plurality of scallops or other gripping members are utilized to facilitate easy gripping and rotation of the rotatable ring.
